Application filed January 19, 1920. seriel No. 352,244;

having interfitting and detachable connection with each other whereby, one of said 1 sections of each railisadapted for receiving most of the wear and newechm y Anotherobject ofthe-invention 1s to. provide a'track construction of the above type capable of being rewherein'the rail sections are cooperatively constructed forreception upon a noveltorrn of tiessoas to present a h1ghly etlic ent and:

durable railway.

-VVith the above general objects in view and others that will become apparent asthe nature of the invention is better understood, the same consists in the novel form, combination and, arrangement of parts hereinafter moreiully described, shown in the accompanying drawlngs'and clalmed.

.' In the. drawings,-wherein like reference characters j.indicjate corresponding 7 parts throughout the several views,

Figure 1 is a transverse sectional view of a track construction embodying the present invention, V

Fig. 2 is a view thereof partially in plan and partially broken away,

Fig. 3 is a perspective view of one of the ties shown in Figs. 1 and 2,

Fig. 4 is a transverse sectional view illustrating a Inodifiedform of the invention,

Fig. 5 is a similar view illustrating a further modification. of the invention,

Fig. 6 is a perspective view of the wear receiving rail section of Figs. 1 and 2,

Fig. 7 is a similar view of the other section of the rail, and

Fig. 8 is a fragmentary perspective view illustrating the application of the invention to switch or crossing rails.

Reterring more in detail to the several views, the present invention contemplates the provision of a rail composed of two longitudinal sections 5 and 6 which are disposedside by side as shown in Fig. 1. The lower portion of the section'G is outwardly flanged, as at 7 and is provided'with the usual ball or tread memberv 8 at its upper edge. One side face of the rail section 6 is cut away as at 9 so as to form a rabbet .vithin which the upper portion of the rail section 5 is seated, andthe rail section 6 has a longitudinally extending rib 10 upon its, inner face within said rabbet. The-rail section 5 is formed with a complementalgroove longitudinally of the inner side face thereof as at 11 so as'to snugly receive the rib 10 where-,

by the two rail sections 5 and 6 inter-fit. The sections 5 and 6 may be retained operatively related by any suitable means, said means being herein illustrated as comprising a pluralityof.stud bolts or screws 121which are passed through suitable perforations 13 provided in the webpf thesection. 5 and which are threaded into sockets ll provided sections 5 and 6. are thus effectively joined so as to provide a rail whichissubstantially as durable as a one piece rail, andthesection in thesections 6 at suitable intervals. The i 6 may be renewed from times to time as found desirable by reason of breakage or undue wearing thereof. Obviously, the secbear and run, The section-5. is also oute wardly flanged at its lower edgeas (1.5151 so that the .two flanges? and 15 jointly form" substantially the usual flange base-such as is."

commonly found upon one piece rail constructions now 1n use. I The structure 1s made somewhat more durable by the provision of a novel form of tie 16 best shown in Fig. 3. This tie isot the usual form with the exception that the same is provided with seats 17 at its opposite ends constituted by undercut transverse. grooves which are of such depth as to ac-' commodate the flanges 7 and 15.

The

grooves forming the seats 17 being under- 7 out, the sides 18-ofsaid seats converge upwardly toward each other and contact the chamfered edges 19 and 20 respectively of the flanges 7 and 15 whereby the rail sections 5 and 6 are effectively held in their seats 17. The seats 17 are thus of substantially dovetailed formation as is also the base of the rail formed by the flanges 7 and 15. It is tobe understood that the sections'5 and 6 are 7 slid longitudinally into the seats 17 to their proper positions.

Each seat 17 of the tie 16 is provided with a central longitudinally extending upstanding rib 21 which is preferably of inverted V-shape in cross section, and the rail sections 5 and 6 are both outwardly cham'l ered as at 22 at the lower portions of their meeting faces so as to provide a groove oi such form as to snugly receive the 'rib 21. This form of seat in combination with the particular rail used produces a very durable track con struction. V

In Fig. 4, the construction shown is sub stantially the same as that of the embodiment above described with respect to Figs. 1 to 3 inclusive and 6 and 7, with the exception that the inner rail section 5 is formed also with a head 8 and acts as a guard rail in the usual and well known manner.

In Fig. 5 a construction is shownwhereby removal of the rail sections may be had without sliding the same longitudinally out of their seats 17. Thisis accomplished by inclining the contacting faces 23 and 24: of the'rail sections 5 and 6 upwardly and leaving a slight space as at 25-between the free edge of the flange 7 and the adjacent side Wall 18 of the seat 17 whereby, when the screws 12 are removed, the section 5 may be tilted away from the section 6 and bodily removed by an upward pull.

In Fig. 8, the construction ofthe rail is substantially the same as shown in Fig. 1 With the exception'that the rail section 6 is provided with an enlarged and laterally eX- tended head 26 which overlies and rests upon 7 the upper edge of therail section 5 and is to form the usual switch or crossing track.

as will be apparent.

In v1ew of the foregoing descrlptlon, it is believed that the construction and operation of the present invention as well as the advantages thereof will be readily understood and appreciated by those skilled in the art.

It is to be understood that minor changes may be made in the form, combination and arrangement of parts without departing from the spirit and scope otthe invention.

What I claim as new is: V

1. In a railway track construction, a rail composed of a pair of longitudinal sections positioned side by side and each having outwardly directed base flanges, one of said rail sections being provided at its upper edge with a ball and being rabbeted at one side for the reception of the upper portion oi the other section, one of said sections being provided with a longitudinal rib upon its inner face, the other section having a com plemental longitudinal groove receiving said rib, means 'to fasten the rail sections together, said rail sections being chamtered at the lower portions of their inner faces to provide a substantially inverted V-shaped groove, a railroad tie having a transverse seat formed therein for the reception of said base flanges of the rail sections, and an upstanding substantially inverted V-shaped rib longitudinally and centrallly disposed in said seat and received within the groove of the rail.

2. The combination with a railroad tie having a'transverse seat formed therein by an undercut groove, of a rail resting in said seat and having dove-tailed engagement with the latter 'said rail comprising a pair of longitudinal separable sections, one of said sections being provided with a rail head and being adapted to be renewed, the base OifSttld rail being provided with Lt longitudinal inverted ll-shaped groove, and a central upstanding rib formed on the tie centrally of the seat thereof for snug reception within the groove of the rail.

In testimony whereof I afiix my signature.
